Not shown as logged in on some pages

Hi,

I think I am facing few issues as listed below:

1. On few pages, I am not shown as logged in. i.e. Even though I am logged in but on those specific pages I see the username, password and login button at the top. If I switch to other page, I can see a normal page with Notifications, My Profile, Settings button at the top.
One such example is
http://www.blackhatworld.com/blackhat-seo/f76-hire-freelancer/

Please see the attached images.
Not logged in:



As soon as I switch to other page, I am shown logged in:



2. Yesterday I received an email saying that I got a PM from one of the member here. I saw the content of the PM and decided to respond. But, surprisingly I don't see that PM in my Inbox.


Can the technical team look into these issues.

Thanks
